i guess what i really want is Arena style but the back drop be Warsong Gulch...

What would I need to do to create a custom battle ground area? Using the WarSong Gulch map? I know there are NPC entries in the Battlemaster_entry table that point to a bg_template I would create another entry in the BG_template table say id 9 however where are the BG templates defined? and how would i add another option?
